Budget Friendly Foxbody Rear Disc Brake Upgrade (Please note: I have Rotors backwards in the video)
ฝัง
- เผยแพร่เมื่อ 10 ม.ค. 2021
- I found a budget friendly rear disc brake kit from Foxbodybrakes.com for around $500. I added the parking brake cable for another $100. I will show you how I installed this kit. I do not show bleeding the brakes as there are plenty of videos doing so.
******** I need to point out I made a mistake in the video. The rotors are directional so I have them reversed. *********

Parking Brake Cable: foxbodybrakes.com/collections...
They are D627 pads, SN95 Cobra pads.

I had never heard of this company before, thanks for the info and the kit looks nice.
The brakes actually ship from Baer Brakes. I’m very happy with the setup. FYI I only had the brake lockup once. Been fine since.
Very nice. I have that same rear kit. I purchased their first 4 lug 13 inch front brake kit.
Beautiful Mustang man,i have a 89 and a 91,91 since new, both are in so so condition, i have drive then and drive them, been wanting to do this for a long time, excellent video also, enjoy watching someone that knows how to work with tools,good job.
Thanks. I am real happy with the brakes. It only locked up that one time. Probably because I didn’t break them in before trying a hard stop. This is a fun car to drive.
Awesome vid, very thorough and well done
Wow!!! I just looked at that kit. Definitely getting one. Great find!!
I did mine myself last summer. Stops great & looks BAD AF!
On the parking brake cable, there is a side that looks like a ball, and one that looks more like a cylinder. It looks like you pushed the ball side through to the parking brake, that side is actually smaller than the cylinder side. I'm measuring the ball side at around 12.4 mm and the cylinder side at around 13.4 mm. When pushing the ball side to the caliper, and the cylinder side to the parking brake - it all fits.
And thanks for the video, I watched it multiple times along with a few others before I attempted this on my ride!
Great video man it's spot on a good tool for anyone 👍
This video just saved me a bunch of headaches! Everything I need in a nice convenient package!
Glad it helped you. I am very happy with the brake package. The guys at Fox Body Brakes were very helpful. I only had the right brake lock up once. Hasn’t happened since.
@@fixthemthings does Foxbody brakes.com have a contact number or is email their only way of communication?
@@frankenstanggarage7911 they just do email but reply pretty quick.
Great video, will be trying it on my foxbody’s
Pretty good video. Keep them coming.
Thanks for making this video, just ordered my kit today thanks to you.
How is the kit working for you?
@@MultiTestPage I have had no issues at all. Braking is great, highly recommended!
@@evanobrien2429 thanks!
Thanks for the video, it was very informative 👍🏿😂
Great video. Nice conversion.👍
Thanks man. It is well worth it. I highly recommend doing it. Of course, if you want to spend more money you can go bigger but I don’t think it is worth it.
@@fixthemthings I did the same but I use used parts for my setup with some new parts as well. You can see it on my channel. Your video came up on my feed so I watched it great work keep it up.💪
Great video! You should do more Foxbody content.
Thanks. I would but I have nothing to upgrade right now. I have it like I want it. 332,000 on it now. Once it dies (don’t think it will) I will probably do a new 347 with fuel tech.
Whoa this is way easier and cheaper than some of the other solutions I've looked at. Thanks!
It is well worth it. The stopping power is not much more but it is better. I’m very happy with the brakes.
@@fixthemthings I have an 86, I upgraded the front spindles to later model and went with a Powerstop kit for 87-93, that was a night and day difference, can't wait to do the rears!
Great vid! Brakes are a real shortcoming on Foxbodies! Glad to see an affordable kit thats not 2k$. Did you let the company know about that hole in the Caliper being to small? And did you do a vid on rebuilding the trac loc clutches? Id love to see it, as it seems the Ford Motorsport Trac loc 28 spline may be discontinued now..Again great vid!!✌🏾
Thanks. I contacted them about the hole size. They said they thought all of them were fixed. I guess mine was overlooked. I love the brakes. I only had the one lockup. It was probably because of doing the video and doing a quick hard brake test before breaking them in. I don’t plan on doing the clutch packs until they are worn again.
Awesome video. Can you put one up about brake lines or proportioning valve install. 😁🤣
I think LMR has a video on that if I remember correctly.
Save up a bigger pile of money and do the complete 5-lug conversion at one time. Any 94-95 Mustang (or a 96-04 if you go to an aftermarket k-member) is a donor for the hard parts (spindles, axles, etc.). You'll have a huge selection of wheels to choose from and can easily move up to serious brakes in the future. Maximum Motorsports can help if you need parts and advice.
Cool! I want!
Hello I bought this 500 kit, have problem brake s not closing. Any tips, do I need another part not shown.
Dope🎉,,,,,,,thanks
There is a GT kit with 10.5 rotors that the web site says is for 15" wheels. Seems very reasonably priced with the parking brake cable.
Solid video! I like it man! I missed it, was there a proportioning valve in the kit at all or did you just send leave the OEM one in?
No proportioning valve needed. The cylinders aren’t big enough to warrant one. The brakes are working great. I don’t have any brake lock ups. Only one lockup from not doing proper break in for video purposes.
Thanks for the feedback!!
@@mathewshackelford8037 The proportioning valve has nothing to do with the size of the calipers or cylinders,it has to do with the rear and front brake bias and when you install rear discs is almost mandatory to get a valve since drums and discs are totally different animals and requires a little more fine tuning than the non adjustable proportioning valve the cars come with can give.
I believe what the op might be referring to is the master cylinder, if you get big boy brakes up front then you need a new master cylinder but if you only fool with the back brakes then you dont, maybe hes been lucky and everything is working great and thats good, but i would get a proportioning valve and adjust it accordingly.
@@dntlss i know how a proportioning valve works. You notice I never mentioned calipers or cylinders, I simply asked if it came in the kit or if he left the oem one because he never covered that.
I would have absolutely put a 4-wheel disc proportioning valve in the car, just as I did all my 4-wheel disc swaps.
Great video. Only question i have is, did you have to change the proportioning valve?
Reading other comments question was answered. Great vid.
I had already done a 5 lug swap (drums), but with 18" Saleen rims, the drums were ugly af! This was a relatively easy install. Maybe hour & 1/2 per side. COULD NOT figure out the e brake! Mine's an automatic, so I said screw it. LOL Wish I could post pics!
How are the brakes working so far?
Absolutely incredible! The look alone blows ppl away!
@@patrickmcgrew9333 what horse power & brakes do you have upfront?
Had the same issue with parking brake. Doesn't fit. What about the slack in cable? Seems long. Everything else worked out so far. Pads are a bitch with them clips. Seems real tight. I added proportioning valve and gutted prop valve. I have to figure parking cable and bleed everything. Did a complete rear rebuild figured might as well add disc. 👍
If you haven’t got it there should be an adjustment under the console to let slack out of the cable it’s a pain to get the cable hooked up
Nice job chief. I have an all original 1989 Mustang GT with 165k in showroom condition and curse those drum brakes anytime I service them. Are the rear disc replacement pads for an SN95 car?
I think they are however it would be best to ask Foxbodybrakes.com. I’m really liking the brakes. No wheel lock ups like I said in the video. Was just the one time. By the way, the parts are all brand new and ship from Baer.
I think that’s just a Foxbody thing. I put SVO/TBird discs on my LX and get a right rear lock up too
Hey man, I had actually just bought those caliper mounting plates off ebay recently for my own conversion. I had no idea the guy had an actual website. I won't be throwing them for another month or so and was wonder how well those have help up for you and if you've had any issues with them?
I am very happy with them. The comment at the end of my video saying that I had a right wheel lock up was only the one time. I should have broke them in first but for the video I wanted to do a fast stop. This was an easy install. The braking is better and I don’t have the drum noises anymore. I highly recommend since you don’t have to change the master cylinder or brake lines. The new parking brake cables are a must.
Thank you for doing this. Have a 93' Cobra and now my Dad's 91' GT we've had since new, and the 91' is needing some TLC after being a daily for 30 years. My idea is the make the 91' a Mountain "Touge"/Circuit setup because the car had always loved curvy roads but I noticed the brakes are a massive weak spot when trying to work the car into a corner. So when I started tearing the car down I decided the brakes and the cars wiring are going to be the first thing I build from scratch. This helped me alot watching this so thank you.
And just an idea for maybe doing it cheaper, the 93' Cobra uses either a thunderbird or mercury rear disc setup if not mistaken, so if you can find what car from the 80's SVT used when building the cobra you may be able to source a rear disc setup used (You will need the brackets for conversion though)
Good luck all, and remember to be careful in the rain especially. These old foxes don't have good brakes and no ABS, and when someone pulls out in front of you things can get sketchy..
Good luck everyone.
That is one clean foxbody undercarriage! Did you change the prop valve and master? The fluid volume required to lockup will change drum to disk and you should look into that.
Well, it has been garage kept it’s whole life. The lockup only happens if I hit it as hard as I can which I probably shouldn’t have done yet as it needs to break first. I would think both should lock up if it was a proportioning valve problem. I’m thinking I should have went ahead and did the clutch packs. I was too lazy to fumble with the spring and said “screw it.”
@@fixthemthings I was more referring to rebalancing your line pressure front versus rear. Do your front brakes lock up before the back? I know back in the day when we either gutted the proportion involved or put in an adjustable proportioning valve. And of course change the bore of the master cylinder by replacing with a 93 cobra type or aftermarket but people were doing more bear brakes and things back then. I've done a turbo coupe rear disc setup as well as baer tiring 12" and to get the brake bias proper I had to modify both the MC and prop valve. Of course that won't affect side to side pressure just front to back
@@TheTTVert maybe the left side doesn’t lock up because of my fat ass on that side. Could be proportional problem. I’m not gonna worry about it because it is only when I stand on it. Oh and by the way these brakes were sent from Baer.
Who's kit is this does it include good comprehensive detailed instructions and how much time did it take to complete ? Car looks really good ! Thanks👍
The links are in the description. Shipped from Baer brakes. I would say half to full day depending on skill level.
Without this video, I could NOT have done it. 4 pages of not so detailed instructions were trash!!
Kit comes with 2 brackets. What's the 2nd one for? I don't see in your video.
spacer. 👍
Ever figure out why the right wheel was locking up? I'm interested in putting this kit on my fox.
Actually it hasn’t done it since. I slammed the brakes on that day after installing. I probably should have broke them in first but to finish the video I went ahead and tried slamming the brakes. I measured my body height yesterday to see why my car was leaning. I guess my fat ass is weakening the springs on the drivers side. Maybe the height difference would affect the braking.
@@fixthemthings sounds like Richard Simmons could help with your 60-0 time.. 🤣
What about the proportioning valve , did you change it as well ?
No you won’t have to change it for these brakes. That is what is nice about it. Everything else stays original.
Those look exactly like sn95 rear brakes .
@@Lxmustang805 I think they are, just brand new.
When these brake pads needs to change in future, how i find it? how ask for these in the dealer? what's the part number ??
Good question. I thought the same thing. They are D627 pads, SN95 Cobra pads.
Did u have to purchase new hard lines for the rear?
No just bent them to shape.
I heard that rear disc conversion won’t fit with the pony wheels, has anybody experienced this themselves?
I already did 5 lug axles 1st, and the 18" Saleen rims fit and look perfect!!
@@patrickmcgrew9333 I dont think he was asking about 18 inch wheels,hes asking if the original pony wheels will work with the rear disc brake setup.
For the e-brake, did you modify the handle to remove that adjuster that is built into it?
No modification necessary.
Thank you! Great video!
Mine is an automatic, so I said screw that e-brake. LOL
@Fix Them Things! hey what's the difference between the lmr kit and this one I just bought the lmr kit and the video shows e brake being modified and don't know why you didn't have to do it I'm considering sending my lmr kit back your thoughts on what is the difference of not having the e brake modified
Did you have to add a brake proportioning valve for the rear?
No. Not for this setup. You can ask foxbodybrakes.com to confirm.
I bought the prop valve and plug. They said you should for adjusting
What can happen from putting the rotors on backwards
Well. The air fins are made to turn a certain way for cooling the rotors. They wouldn’t have cooled as well. I don’t think it was a big deal but I didn’t want to put out any misinformation on my videos. After you load a video on TH-cam you can’t really change it so I updated the description and title.
@@fixthemthings thanks for the feedback
Did you reuse the factory master cylinder?
Yes, everything else is factory. If you go bigger on the caliper then you would have to start changing the factory stuff. Mine is doing great.
@@fixthemthingshow's the rear breaks working so far? Can you drive it daily?
What size wheel you running?
245/45/17.
My shop/mechanic is saying (after I installed these PERFECTLY) that I need a proportioning valve. Please advise.
Not for this size of piston. If you go with bigger brakes you will need proportioning valve. I verified this with Baer brakes also.
@@fixthemthings so I DON'T need a proportioning valve??
@@patrickmcgrew9333 No. You can put one on if you want but it will have to be wide open anyway. I wouldn’t put one on. In my video, I had one wheel lock down when I slammed on the brakes. I haven’t had a lock down since. When I did the video, I did not break in the brakes. I should have waited until break in to do the hard brake test. I hope that helps.
@@fixthemthings just FYI, the shop has had my 90 gt for one total month now and can NOT get the rear brakes any brake fluid.
@@patrickmcgrew9333 you must have a stuck valve on the original parts. The brass part under the master cylinder. I can’t attach a picture here to show you. If you take the big nut of of the front side of the brass piece you will find the orings all chewed up and the plunger is probably stuck. There is a rebuild kit for that online.
Did you have to do anything to your brake booster?
No. Everything else is stock. The caliper cylinders are not much bigger so not needed. I’m very happy with them now.
@@fixthemthings thanks for the info
Did you modify the parking brake paw?
No I didn’t have to modify it. It works just like the drum parking brakes. I really like the brakes now.
@@fixthemthings Manual trans?
@@drdyno yes
No prop valve or plug. Do you need it?
Don’t need it for this setup. If the calipers were bigger, then yes.
I bought it cause they told me to. I have to replace brake line because it was a 4 banger. I guess it can't hurt to add it.
No worries.
Yes you would want to get cables (we list 78-92, and 93 cables) in other auctions. I would recommend a prop valve (adjustable), and our prop valve plug. This should be all that is needed.
In some cases if your handle self tensioner is worn out you might need the short adjustable cable, but we always recommend installation first as many do not need it. This was foxbody response. Guess it can't hurt. How do you adjust it?
@@timsimons8946 which brake line did u have to replace? Mines was a 4 banger converted to 8. Wondering if mines was done already but I still have drums 5lug
Hate to say this, but I bought this rear kit, had it installed and did not notice any difference in stopping power. I'm going to have another mechanic look it over for a 2nd opinion.
have you got proportional valve installed? you may need to adjust that to add more rearward brake pressure..
@olliej914 thanks for the pro tip, I will relay to my mechanic.
Since the rear brakes do about 30% of the stopping you may not notice a difference. The advantage of disc brakes is a greater resistance to fade. The ultimate limitation of a brake system is the amount of grip at the tire contact patch.
@@MultiTestPagedid you add a prop valve? Im about done with mine and wanna know if i need a valve
We installed the proportional valve an will test drive in a few days. Thanks for your advice. I'll let you know how it drives.
Will this kit fit with 15x10 wheels??
That would be a good question for Fox Body Brakes. They are great about returning communications. I would think so though.
@@fixthemthings A 15 inch wheel will not fit. I tried...
@@mikeedwards1656 contact with the calipers? I really like how complete this kit is.
I was told 10.5 gt kit will fit 15 "
Was this the gt kit or cobra kit ?
Cobra
@@fixthemthings thank you
